PTR-TOF 8000 and PTR-QMS

Affiliation: University of California at Berkeley, California, USA

IONICON instruments: 1x PTR-TOF 8000; 1x PTR-QMS

Contact person: Prof. Allen H. Goldstein

“Why is an IONICON PTR-MS very well suited for your measurement tasks?”

Prof. Goldstein told us: "We use IONICON PTR-MS and PTR-TOFMS instruments for real-time measurements of a broad array of VOCs in the atmosphere, including ecosystem and aircraft scale flux measurements, direct emissions from plants and microbial cultures, controlled laboratory oxidation studies of VOC reactions and secondary aerosol formation, and field studies of atmospheric chemistry and air pollution. The rapid response and low detection limits made possible by these instruments are critical to our scientific investigations."
